thingiverse

1.25 inch focuser for Dobsonian telescopes features a versatile mounting system that allows users to attach it flat or in a tubular configuration. The focus stroke is designed to deliver precision, with a 30 mm travel range. Engineers have carefully crafted the mechanical interface, ensuring the mounting screw hole measures exactly 4 mm in diameter. To prevent damage and improve optical performance, eyepieces are not intended for direct screwing onto the focuser. Instead, they should be securely fastened using the manufacturer's recommended attachments. This design update was introduced as part of a new model release on February 23rd, 2017, aiming to eliminate looseness issues associated with earlier models.
